Английская Википедия:GNR Class J23
Шаблон:Use dmy dates Шаблон:Use British English Шаблон:Infobox locomotive The Great Northern Railway Class J23 was a class of Шаблон:Whyte steam locomotive. They had long side tanks that came to the front of the smokebox, which sloped forwards to improve visibility and had a recess cut in to aid maintenance. Forty were built by the Great Northern Railway (GNR) between 1913 and 1922, with a further 62 being added by the London and North Eastern Railway (LNER) between 1924 and 1939. They were given the nickname "Submarines" due to their long tanks.[1]
History
For shunting and local goods work, the Great Northern Railway (GNR) had traditionally used saddle-tank engines of the 0-6-0 wheel arrangement; the last of these, of GNR Class J13, having been built in 1909 to the designs of Henry Ivatt, the GNR Locomotive Superintendent.Шаблон:SfnШаблон:Sfn
Nigel Gresley succeeded Ivatt in 1911,Шаблон:Sfn and soon identified a need for engines to work the short-haul coal traffic in the West Riding of Yorkshire; the nature of which required that the locomotives also be suitable for shunting. He designed a new class of Шаблон:Whyte engine, using side tanks instead of saddle tanks.Шаблон:Sfn Gresley had recently begun the rebuilding of the GNR Class L1 Шаблон:Whyte locomotives with larger boilers, Шаблон:Convert in diameter,Шаблон:Sfn which left a number of Шаблон:Convert diameter boilers spare. Thirty of these were used in the construction of the new goods tank engines between 1913 and 1919;Шаблон:Sfn when ten more were built in 1922, these again used secondhand boilers, but Шаблон:Convert in diameter.Шаблон:Sfn On the GNR, both varieties were classified J23, but the LNER divided them into J51 with smaller boilers, and J50 with larger boilers.Шаблон:Sfn The LNER continued the construction of Class J50, building a further 62 up to 1939,Шаблон:Sfn only the first ten of which were given secondhand boilers.Шаблон:Sfn Class J51 were rebuilt to class J50 between 1929 and 1935.Шаблон:Sfn
Each of the two main classes exhibited variations: locomotive brakes could be operated by vacuum or steam pressure; the driving position could be on the right- or the left-hand side of the cab; and there were three sizes of coal bunker. These variations were recognised by class subdivisions:Шаблон:Sfn
- J51/1 10 built 1913–14, 4 ft 2 in boiler, vacuum brake, right-hand drive, short bunker
- J51/2 20 built 1914–19, as J51/1 but long bunker
- J50/1 10 rebuilt 1929–35 from J51/1 with 4 ft 5 in boiler
- J50/2 20 built 1922–24, as J51/2 but 4 ft 5 in boiler, plus 20 rebuilt 1929–34 from J51/1 with 4 ft 5 in boiler
- J50/3 38 built 1926–30, 4 ft 5 in boiler, steam brake, left-hand drive, long bunker
- J50/4 14 built 1938–39, 4 ft 5 in boiler, vacuum brake, left-hand drive, long bunker with hopper
All were built at Doncaster, except the last fourteen which were built at Gorton.Шаблон:Sfn Further orders were placed in 1939 and 1941 totalling 25 more locomotives, but these were cancelled in 1942 after a number of components had been manufactured.Шаблон:Sfn Withdrawals began in 1958 with the arrival of diesel shunters and ended in 1963 for the normal stock. 7 of them survived as departmental stock until 1965. The class became extinct in September 1965 when Departmental No. 14 (ex-68961) was withdrawn and scrapped. None of them survived into preservation.[2]
Numbering
On the GNR, the numbers were 157–164, 166–176, 178, 211–230; these were increased by 3000 by the LNER.Шаблон:Sfn The first ten engines built by the LNER were numbered 3231–40, following on from the GNR engines;Шаблон:Sfn but those built from 1926 were given scattered numbers between 583 and 636, between 1037 and 1086, and 2789–94.Шаблон:Sfn
In 1943, new numbers were allotted in a continuous block from 8890 to 8991; these numbers were applied between January and December 1946,Шаблон:Sfn but before this could be done, the oldest ten, nos. 3157–64/6/7 were temporarily renumbered 3180–9 in May and June 1945. They duly received their permanent numbers 8890–9 between June and December 1946.Шаблон:Sfn Under British Railways, the 1946 numbers were increased by 60000.Шаблон:Sfn
